Practice Problem: Determine if X and Y are independent
Two continuous random variables X and Y have the following joint probability density function:
$ f_{XY} (x,y) = C e^{\frac{-(4 x^2+ 9 y^2)}{2}}, $
where C is an appropriately chosen constant. Are X and Y independent? Answer yes/no and give a mathematical proof of your answer.
